BUG: DCOM Client Hangs and Then Gives Error 429
SYMPTOMS
=========
When running an ActiveX EXE Server created through DCOM on a Windows NT or
Windows 2000 machine, the client may hang for approximately 2 minutes and
then generate a run-time error:
'429' - "ActiveX component can't create object".
CAUSE
====
This is caused by the ActiveX EXE Server trying to write to a registry key
that the User Account the DCOM Server is running under does not have
permissions for.
RESOLUTION
========
The workaround to this problem is to set the permissions to the given
registry key so that the User Account running the DCOM server has full
control or, at least, setting and querying rights.
IMPORTANT: This article contains information about editing the registry.
Before you edit the registry, make sure you understand how to restore it if
a problem occurs. For information about how to do this, view the "Restoring
the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key"
Help topic in Regedt32.exe.
WARNING: Using Registry Editor incorrectly can cause serious, system-wide
problems that may require you to reinstall Windows to correct them.
Microsoft cannot guarantee that any problems resulting from the use of
Registry Editor can be solved. Use this tool at your own risk.
Allowing Full Control on the Given Registry Key
o Open the REGEDT32 tool and select the registry key below:
HKEY_CLASSES_ROOT
\CLSID
\{D5DE8D20-5BB8-11D1-A1E3-00A0C90F2731}
o Select "Permissions" from the "Security" menu.
o Click the "Add" button and give "Full Control" for each DCOM client user
account that will need to access the DCOM Server.
Allowing Setting and Querying Rights on the Given Registry Key
o Open the REGEDT32 tool and select the registry key below:
HKEY_CLASSES_ROOT
\CLSID
\{D5DE8D20-5BB8-11D1-A1E3-00A0C90F2731}
o Select "Permissions" from the "Security" menu.
o Click the "Add" button and give "Special Access" for each DCOM client
user account that will need to access the DCOM Server. In the Special
Access window, select the Set Value and Query Value boxes.
Who Needs to Have Access Rights to This Key?
The users you need to give access rights on the key mentioned above depend
on your Identity setting in DCOMCNFG, as explained below:
o The Launching User:
If your server will run under the context of the Launching User, you will
need to grant rights to each user account that will need to access your
DCOM server.
o This User:
If your server will run under a specific User Account, you need to grant
access only to this user.
o The Interactive User:
If your server will run under the Interactive User account, you need to
grant access to the Interactive User.
NOTE: When the identity is set to This User, DCOMCNFG will add This User to
the list of accounts with rights to "Log on as a Batch Job." In a very
specific situation, this may not happen. This is a known bug in DCOMCNFG.
If you are under this situation, you should add this account manually using
the "User Manager" Administrative Tool for NT. From the Policies Menu,
select User Rights, check the "Show Advanced User Rights," select the "Log
on as a Batch Job" option, and add the required user to the list.
STATUS
=======
Microsoft has confirmed this to be a bug in the Microsoft products listed
at the beginning of this article.
MORE INFORMATION
===============
You may also note that the ActiveX EXE server process is launched and
running on the Windows NT or Windows 2000 system during this 2-minute
timeout period. The CPU utilization for this process will most likely be
close to 100 percent. At the end of the 2-minute period, the Server process
will go away.
